I haven't looked at the code but based on the error above, if you
change line 414 to:
$scan->{'admin'} = 1 if( ( defined $opts ) && ( exists $opts->{ADDADMIN} ) && ( $opts->{ADDADMIN} == 1 ) );
your particular error should go away.

You'll also want to change line 90 to:
if( ( exists $opts->{'MUST-ADMIN'} ) && ( $opts->{'MUST-ADMIN'} == 1 ) )

I suspect there is something else broken in the code though to cause
these hash elements to not exist in the first place.

You'll probably do best to contact the author of the code
(julien.delange () gmail com).
